Bener Meriah district is one of the arabica coffee producing regions in Indonesia with an average production of 700-800 kg ha-1 year-1. Most of arabica coffee in this area are grown in Andisol. This study aims to determine the P status of Andisol, namely P-available, P-total, P-retention, P content of arabica coffee leaves and the correlation between soil P-available and P content of arabica coffee leaves in Bener Meriah district. This research was conducted using survey methods. The observed parameters were made on Andisol planted with arabica coffee which is located at an altitude of 1,200-1,400 m above mean sea level (AMSL) at slopes 0-3, 3-8, 8-15, 15-30, and >30% respectively. The results showed that Andisol Bener Meriah has a P-available ranging from 0.3 to 12.81 ppm (very low-high). Most of the Andisol observed (73.33%) had P-available at very low and low levels. Andisol Bener Meriah has a P-total ranging from 159.4 to 1,246.7 ppm (low-very-high). Most of the Andisol observed (73.33%) have P-total at moderate, high and very high levels. Andisol Bener Meriah has a P-retention ranging from 85.2 to 87.4%. Arabica coffee leaves have P content levels ranging from 0.10% to 0.23%. Most of the arabica coffee leaves (78.57%) were observed have P content at a minimum level.; there is a close relationship between soil P-available with P content of arabica coffee leaves with a value of r = 0.97. © Published under licence by IOP Publishing Ltd.
